Case Example: Boundary Interference

Consider a recio where a speaker is placed two feet from a front wall. The wall creates a reflection that arrives slightly delayed from the direct sound, causing a serie of cancellations and concements at specific encidencies - known as thes Speaker-boundary interference response (SBIR)Moving the speaker closer or farther changes the cancellation dip frequencies.

Practical Etapy for Optimal Setup

Adjuss toe- in by ear or by measuruing thee frequency response at the listening position. Check for SBIR dip frequencies using REW or simular dispalare.
  4. Place subwoofers using thee crawl technique. If using two subs, try opposite wall midpoints or along thee front wall at 1 / 4 and 3 / 4 positions. Measure the low-frequency responsy at the listening position for each candidate location.
  5. Take baseline measurements. Use a calilated USB microphone and REW or similar dispare. Capture frequency responsy and impulsy e response at te e listening position. Note major peaks andd dips. Save this measurement for comparison.
  6. Make Minor adjustments. Move speakers an inch or twor and re- measure. Look for the smartthest responses befor e applicying EQ. Small changes can move dips and peaks consignitantly. Document thee final placement distances for peyablity.
  7. Run room correction (Dirac, Audyssey, etc.) following thee exirer 's procedure. For advanced users, generate custem target curves that conserve thee speaker' s natural roll- off rather than forcing a flat responses to o 20 Hz. Use a gentle housie curve that matches your listening preferences.
  8. Po-correction listening andtweaks. Listen to familiar tracks. If the sound is too bright or dull, adjuss the target curve or use a gentle shelf filter. Avoid making large EQ moves after correction. Verify with metriurement that the correction is working as intended.

Another advanced technique is manual target curve design, were you create a cresmm frequency responsy target that accounts for room gain, speaker limitations, and personal preference ce. Many professionals calisators use a target curve that slopes downward slightly from the bases to the treble, mimimicking the e natural in- room response of a well- tuned system.
